How do you use a flat block on a curved surface like a rear quarter panel ?

Experience and skill. An in-line air sander is basically a powered 2 X 4. On a curved surface like a quarter panel, the technique is to start at the extremities of the bondo patch and work towards the crown. After the plastic was formed using 36 grit the scratches were smoothed with 80 grit. The area was then sprayed with primer and then coverd with red putty using a squeegie. A rubber sanding block was used to wet sand the putty with 100 grit to fill the minor imperfections. After a final primer coat and sanding with 320 grit the area was color sprayed. Anyone with basic mechanical skills could learn autobody work with a little practice. A good skill to develop if planning to do restorations.
